Snow blower friction wheel urethane rings

What determines the working life of the friction disc?

First, from the material from which it is made. If the metal part is steel, the disc will last longer than the one made of aluminum. A high-quality seal that fits over the metal disc, that is, the friction ring is the next important element. Most often, rubber is used as a seal material. The rubber ring wears out very quickly.

If you replace the worn rubber friction ring with a more wear-resistant polyurethane one, you can operate the snow blower for much longer without replacing the friction ring.

It is also necessary to pay attention to the operating conditions of the snow blower, namely:

• do not frequently and unnecessarily change gears while the machine is in motion;
• do not strive to immediately remove a large layer of snow, especially drifts;
• consider the power of your snow blower.

How often should the clutch ring be replaced? How do you know when a replacement is required?

If the instructions do not specify the recommended frequency of inspection and replacement, it is recommended that the ring be checked for serviceability after every 25 hours of operation of the snow blower. By installing a polyurethane ring, the inspection time can be doubled.

If, when starting the snow blower, it does not start or slips, check the serviceability of the friction ring, drive belts and drive gears. It is important not to wear the seal to such an extent that the metal disc begins to wear out. In this case, repair and replacement of the unit will cost significantly more.

Friction rings manufactured by Polyurethan LLC

The company «Polyurethan» has experience in the manufacture of friction rings for more than 10 years, constantly in the warehouse there are friction rings for all popular models of snow blowers: Arctic, Profi, Interskol. It is also possible to manufacture non-standard under the order.

Friction rings can be purchased in sets. This will help to save money, because in the sets the rings are cheaper per piece, and it will be possible to test rings of different hardness, changing them depending on the operating conditions of the snow blowers. This is especially useful if you have several of the same snow blowers.

How to choose a polyurethane friction ring?

You can choose a friction ring by diameter — inner and outer and by the width (thickness) of the ring, since many models have the same diameter.

Some of the articles of friction rings on our website have several different characteristics (markings). For example, ring number 33-01-614 is produced with the markings PU54/M80, PU54/M87, PU54/K80, PU54/K87. When ordering, you need to select one of them in the product card.

Let’s look at the example of a ring with catalog number 33-01-614, how to choose the right characteristic for the friction ring. Numbers 80 and 87 indicate Shore A hardness. Larger numbers mean higher hardness. The letters K and M denote a different composition of polyurethane, on which the characteristics of the rings depend. Each alphanumeric characteristic has its own color. This is done in order to make it more convenient to distinguish rings with different characteristics.

Stop your choice on products with the M marking if the snow blower will be operated in a climate with severe frost, where temperatures from -20°С to -50 ° C are frequent.

If your snow blower operates in milder climates, where frosts below -20°C are infrequent, choose products with the K mark, and your ring will be more resistant to sprains, punctures and tears.

If you have any doubts about what to choose, our experts will always advise you!

Why buy a polyurethane friction ring?

By choosing a polyurethane friction ring, you will increase its service life by at least 2 times. And with proper operation of the snow blower, the polyurethane friction ring will work 5-6 times more.

It is important to remember one condition: polyurethane is resistant to frost, but does not tolerate heating, so you need to prevent the clutch from heating up, which happens most often when the snow blower is running out of wear!
